Preparation method of Portland cement clinker
The invention relates to the technical field of cement production, in particular to a preparation method of Portland cement clinker, which comprises the following steps: washing shells with water, drying, and primarily crushing the shells with a crusher to form crushed shells; the method comprises the following steps: crushing limestone and shells according to a ratio of (5-15): 1, conveying the crushed limestone and shells to a homogenizing stacking shed for homogenizing, conveying the homogenized limestone and shells to a batching station, batching and mixing raw materials according to the formula requirements of the Portland cement clinker, grinding and sintering the mixed raw materials, and grinding the clinker to finally produce the Portland cement clinker based on the shells. According to the invention, the shells are used for replacing part of limestone, so that the pollution of the waste shells to the environment can be effectively solved, the limestone consumption can be reduced, the greenhouse gas emission can be reduced, the high-quality limestone resource consumption of a low-grade limestone mine can be reduced, the service life of the mine can be greatly prolonged, and the long-term economic benefit is obvious.
本发明涉及水泥生产技术领域，具体涉及一种硅酸盐水泥熟料的制备方法，包括步骤：将贝壳使用水冲洗干净，并烘干，之后使用破碎机对贝壳进行初破，形成贝壳破碎料；按照石灰石和贝壳比例为5～15：1的比例进行破碎，之后输送至均化堆棚进行均化，再送至配料站，根据硅酸盐水泥熟料的配方要求，进行生料配料混合，并将混合后的原料进行研磨、烧成和熟料磨矿，最终生产出基于贝壳的硅酸盐水泥熟料，本发明通过用贝壳取代部分石灰石，不仅可以有效解决废弃贝壳对环境的污染，还可以减少石灰石用量，从而减少温室气体排放，同时可以减少低品位石灰石矿山的优质石灰石资源消耗，大大延长矿山使用寿命，长远经济效益明显。
